UNITED STATES FFICELa ATENT BLOWPIPE.

SPECIFICATION forming part of Letters Patent No.473,19'7, dated April 19` 18.92.

Application filed November 28, 1891. Serial No. 413.430. (No model.)

To all whom t may concern:

Be it known that I, JOSEPH N. PEEBLEs, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Blowpipes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same.

This invention relates generally to blowpipes for the use of metal-workers, plumbers, jewelers, and also for painters, and particularly to that class of apparatus in which a liquid is iirst converted into vapor, which is by its own expansive force expelled in a strong current from the generator through a flame, thereby directing the flame on the object that it is desired to heat, reduce, or fuse, and such vapor-perfecting combustion intensities the' heat of the flame; and it has for its object to provide a simple,durable, easily-operated, and comparatively inexpensive apparatus for the purpose named; and it consists of the parts and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure lis a side elevation of my improved apparatus; Fig. 2, a vertical section through the same, and Fig. 3 a detail view.

Similar letters refer to similar parts in both views.

A represents a tank or vessel, preferably cylindrical, having a screw-threaded opening ct formed in its top, adapted to receive the screw-threaded cap Z7 to close the saine, and B represents a wick-tube screwed to the top of the tank over an opening c in. said top.

From one side of the vessel A,`near its bottom, a spout() projects at an acute angle upwardly, through which a wick is passed, and over this spout a tube d is fitted sufficiently tight to hold it in its set position and loose enough to permit of its being moved up and down the spout in Order to regulate the size of the iiame from the wick in the spout. On

the side of the vessel a handle c is secured.

D represents two fiat upright plates orvbars having their lower ends rigidly secured to the top at its edge and at points diametrically opposite each other, near the upper ends of which are formed the screw-threaded perforationsf, adapted to receive the thumb-screw g, said thumb-screw being formed with the collar 72 as shown in Fig. 3,forapurposetobedescribed.

E represents a vaporizer, in which the steam or vapor is generated todirect the iiame, said vaporizer being formed of a cylindrical tank or vessel having flat bars F rigidly secured to and projecting downwardly from the bottom Of the tank, said bars being pivotally secured at their lower ends to the barsD at the outer sides and near the lower ends of the same, so that said vaporizer may be swung or turned back on its pivots over the tank A, as shown in` dotted lines, Fig. l. formed with a slightly-inclined slot m, cut in from one edge of the bars near their attach- The bars F are each,

ment to the vaporizer, in order that the said7o slots may engage the stems of the set or thumb screws, the collars of which., upon turning the screws, will tightly clamp the bars to the uprights, and thus securely hold the vaporizer in any position to which it may be set within the limit of the slots. To the top of the vaporizer and near its periphery at that side thereof opposite ormost remote from the tubespout C is secured the large end of a tapering pipe G, said pipe iitting over an opening and being attached in an air-tight manner to the top of the vaporizer and extending upwardly therefrom and curving over the top of the vaporizer similar to a handle, and being attached at the Opposite side of the vaporizer to the Wall thereof and continuing' downwardly below the bottom of the vaporizer and having its end curved outward, so as to terminate at a point slightly above and immediately in line vertically with the end of the tube-spout O. In the top of the vaporizer a screw-threaded opening n is formed, through which the liquid is fed, and a cap o provided to close the same and prevent the escape of the vapor generated in the vaporizer.

From the above description it will be observed that the vapor generated in the vaporizer will be expelled in a strong continuous current through the small end of thepipe, and that such current will be expelled with great pressure, owing to the gradual contraction of the pipe to its end where the opening is very small, and will thus cause the iiame from the tube-spout C to be directed out- IOO wardly with great force, the vapor itself igniting and greatly1 intensifying the flame. It Will also be observed that the vaporizer may be turned backward in order to change the angle at which the current of vapor strikes the Iiarne, and thus change the direction of the same as Well as remove the Vaporizer entirely oft the flame from the wick-tube thereunder.

The tube d over spout D may be moved up and down thereon in order to control the size of the iame from said spout by increasing or decreasing the exposure of the wick therefrom.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, in a blowpipe, with a tank or vessel having a vertical central Wicktube and a laterally-projecting wick-tube, of a vaporizer adjustably supported above said Tank or vessel, means for securing said vaporizer in its adjusted position, and a tapering pipe adapted to conduct the vapor from the vaporizer to the mouth or end of the laterally-projecting Wick-tube, substantially as described.

2. The combination, in a blowpipe, with a tank or Vessel having a vertically-projecting Wiek-tube and a laterally-projecting Wicktube, of a vaporizer adjustably supported above said central Wick-tube, and a tapering pipe secured at its enlarged end over an opening in the top of the vaporizer, curving thereover and down alongside said Vaporizer, and terminating at a point slightly above and in rear of the end of said laterally-projecting wick-tube, substantially as described.

3. The combination, in a blowpipe, of a tank or vessel having a vertically-projecting Wick-tube, a laterally-projecting Wick-tube, an adjustable tube for regulating the iialne from said lateral tube, a vaporizer arranged above the tank and adapted to be tilted to one side, means for holding it in its tilted positionv` and a tapering pipe secured at its enlarged end to the top of the vaporizer, curv ing thereover, and terminating at the end of the laterally-projecting tube, substantially as described.

4E. The combination, in a blowpipe, of a tank or vessel having a central Wick-tube, a lateral Wick-tube, and a tube for regulating the flame from said lateral tube, uprights sesured to said tank, a vaporizer, slotted bars secured to and projecting from said vaporizer, thumb-screws for clamping said bars to said uprights, and a tapering pipe secured at one end to the top of said vaporizer, substantially as described.

In testimony Whereofl ailix my signature in presence of two witnesses.
